How do I eliminate UUID dependence?

Executive Summary:

1. I will confirm that this works.
2. I need to vigorously reexamine numerous assumptions, especially wrt grub2 tools.

Great!

Detailed response:
…
Well, that didn’t work.
Why?
A: Because grub2-mkconfig output was not redirected to /boot/grub2/grub.cfg of USB thumb drive.

So either manually edit /boot/grub2/grub.cfg of USB thumb drive, or reinvoke grub2-mkconfig using -o option to direct output.
I chose the latter.
I had used the procedure successfully, but the menu worked only by accident. I assumed that grub2-mkconfig would write to /boot/grub2/grub.cfg but only YAST2-Bootloader does.

Thanks again,
